Play in ten minutes or across a week. The clock sets how long each turn lasts, and you can switch it mid-story.
The Controller can switch the clock during a story; the current turn restarts on the new clock.
Either of you can pause the scene. The clock stops for both of you, you can talk it over out of character, and then carry on or take the last beat back.
Turn on notifications to hear when it is your cue. If your partner has gone quiet, you can nudge them after a while.
